Vapor barrier installation in Longview TX - a drier crawl space under your house

Musty smell or damp air coming up through the floors? We cover the dirt under your house wall to wall so less moisture rises into it.

What does a vapor barrier do under a Longview house?

Vapor barrier installation in Longview means laying a ground cover, sometimes called a vapor retarder, over the bare dirt in your crawl space. When it's put in right, it cuts down the moisture coming up from the ground into the space under your floor.

Most folks call because the floors feel cold or damp, the house smells musty, or whoever came to fix the AC crawled out and said the dirt down there is wet. The price mostly follows how big the crawl space is and whether you keep it vented or close it up. The schedule turns on how clear the space is and whether the city wants a permit, which we check before we start. Your estimate spells out which areas and which materials the job covers, and if the floors still feel cold once things dry out, crawl space insulation is a separate step we can talk about.

How our crew handles vapor barrier installation

We start by hauling out whatever's stored under the house, old boxes, scrap lumber, the odd lawn chair, because the cover has to reach all the ground and it can't do that around a pile of stuff. Then we roll it out over every bit of dirt, run it up the foundation walls and around each pier, and overlap the seams so there's no open strip for moisture to come through. Where the ground slopes or somebody will crawl across it later, we pin it down so it stays put. If you're thinking about closing the crawl space, we'll talk through how the air down there gets dried, since a ground cover by itself won't do that.

Moisture under the floor is usually only part of why a house feels off. Air leaking out the top of the house pulls air up from below, so attic air sealing, which closes the gaps around lights, pipes and the hatch, often goes hand in hand with a ground cover. And if rooms still run hot upstairs or drafty after the crawl space is dry, retrofit insulation adds insulation to the house you already have.

Ground cover with the vents left open

This suits a crawl space that stays fairly dry and has no ductwork running through it, because the cover cuts down the moisture coming up from the dirt without changing how the space breathes. It's the simpler and less expensive way to go, and plenty of houses don't need more.

Closed crawl space with a drying system

This is the one I'd point you toward if the space stays damp or your ductwork lives down there, since you're already paying to cool that air. We close off the vents, seal the cover tighter and add equipment that actually dries the air.

Vapor barrier installation in Longview and what the city asks for

The City of Longview handles construction permits, and whether your vapor barrier job needs one is something we find out from the city before work starts. Contractors apply, pay, request inspections and track review status through the city's permit portal, while homeowners pulling a homestead exempt permit for their own house call or visit the Development Services department instead. If a permit is needed, we take care of it as part of our work and tell you up front.

Longview is the Gregg County seat, though a small part of the east side reaches into Harrison County, and we work on both sides of that line. We're based here and work in the cities around it across East Texas, including White Oak, Kilgore, Tyler and more. A lot of the houses we crawl under around here sit on piers, and it's common to find no ground cover at all, or an old sheet torn and bunched up against one wall.

Questions Longview homeowners ask about crawl space vapor barriers

Should I close my crawl space or keep it vented in Longview?

A properly closed crawl space usually controls moisture better than a vented one, as long as it's done right. National research and real-world jobs show closed crawl spaces can give much better moisture control than wall-vented ones in temperate, humid climates. Closing it is a bigger job than a ground cover, because the design also has to dry the air, so we'll walk through both at the estimate.

Will a vapor barrier help with radon in my house?

It can help, but it isn't a full fix. When it's installed well, a ground cover helps reduce soil gases such as radon along with ground moisture, because it puts a layer between the dirt and the air under your floor.

How do I know if the humidity in my house is too high?

Your house is running too humid if a moisture meter or a humidistat, a small gauge that reads humidity, shows over 60%, which is the line one university extension checklist uses. That checklist says to keep indoor humidity below 60% and suggests a dehumidifier once readings go over it.

What is the best way to dry the air in a closed crawl space?

A closed crawl space needs a mechanical drying system, usually either a small supply of conditioned air from your heating and cooling system or a dehumidifier. That equipment is part of the plan from the start, on top of the ground cover itself. Which one fits depends on how your system is laid out, and that's easier to judge once we've seen it.

How much does vapor barrier installation cost in Longview?

The cost comes down to how big your crawl space is, how much has to be hauled out first, how many piers and pipes the cover has to wrap around, and whether you're keeping it vented or closing it. Closing it costs more because the drying equipment comes with it. You'll get your own figure once I've been under the house.

What should I have ready before you look at my crawl space?

Have your home's address, whether the crawl space is vented or closed, and any humidity reading you've taken. That lets us check with the right building office and come out knowing what we're looking at. If you can, clear a path to the crawl space door so I don't have to wrestle the Christmas decorations to get under there.
